You don't tell us anything else about the engine....any other mods? what the truck is/was used for? nothing about the maintenance schedule? I have to tip my hat to you, you obviously aren't one to 'give up' easy....an 03 and still trying to build it. I hope you get all the 'weak spots' fixed. I'm just driving mine and servicing it on a routine schedule.......when I get something other than good news to report I'll be doing it here, until then....I'll spread the love, lolI have an 03 with 225k. Between the lifters, hpops, head gaskets, egr, injectors....... I'd say they aren't reliable in stock form.
